Can we use data-notify-url attribute to received IPN?

script(src='paypal-button.min.js?merchant=username@email.com', data-button='buynow', data-name='My product', data-amount='1.00', data-env='sandbox', data-notify_url='http://example.com/ipn')

The payment was successful but it seems specified notify_url wasn't called.

I also used Instant Payment Notification (IPN) simulator and enter my notify_url but encountered the error below:

IPN Delivery Failed:503 Service Unavailable

But looking at the logs of my application, I can see the notify_url was called.

I used web accept as transaction type.

This just looks like your Backend-Script (may it be PHP or anything else) is currently not available. It can happen due to a server overload.

The 503 is a HTTP-ErrorCode so it has nothing to do with PayPal. PayPal tries to send the IPN to you and your web-server responds with a 503 error.
